"People don't realize, you know, the Civil War, if you think about it, why? People don't ask that question, but why was there the Civil War? Why could that one not have been worked out?" Trump asked.

Trump said Jackson, who served as president from 1829-1837, would have been able to prevent the war.

"Had Andrew Jackson been a little later you wouldn't have had the Civil War," he said. "He was a very tough person but he had a big heart. He was really angry (with what) he saw with regard to the Civil War, he said 'There's no reason for this.'"

Jackson died in 1845. (16 years before the Civil War.)

Maybe the president should have first discussed Civil War stuff with his resident expert, Alabama's own Attorney General Jeffrey Beauregard Sessions III.
